Driving down a mountain, Tom finds that he has descended 1800 ft
in elevation by the time he is 3.25 mi horizontally away from the top of the
mountain. Find the slope of his descent to the nearest hundredth.
:
One of the definitions of slope is "rise over run", descending means the slope will be negative
:
rise would be 1800 ft, and run would be 3.25 mi,
:
convert 3.25 mi to ft also: 3.25 * 5280 = 17160 ft
:
1800%2F17160 = -.104895, .10 to the nearest hundredth
